Letters Patent .Z Va. 65,559, dated Juice 11, 1867 I IMPROVED Ion-01mm mazes;

TO WHOM IT MAY CONCERN:

Be it known that I, CHARLES Goocu, of Cincinnati, in the county of Hamiltomand Stateof Ohio, have invented a new and useful Ice-Cream Freezer; andl hereby declare the following to be a full, clear, and eitact description thereof, reference being bad to the accompanying drawings, making part of this specification.

This invention is chiefly designed for the class of ice-cream freezers in which the heater or agitator and the receptacle for the cream revolve in opposite directions, and comprisos a form of agitator adapted to sininltancously remove the frozen cream from the sides, and replace it with other portions by an alternate inward and outward aetion,-and a provision -of' wings on the periphery of the can adapted to agitate that portion of the I ice in immediate contact with said periphery.

Figure 1 is an axial section of an ice-cream freezer embodying my improvements.

Figure 2 is a horizontal section at the libs l A is a tub, to whose bottom is attached ar senot the pivot G of the cream-can, or receptacle, D, of cylindrical form. Secured by hooks E E, or other device, athwart' the mouth of the tub, is a transom, F, perforated at its middle forithc stem G of my agitator OG-H I. The cap J of the can Dhas attached to it aspnrwheel, K, driven by a wheel, L,-whose shaft, l, traversing the transom F, has another wheel, L, above said transom,whose motion is derived from the drive-wheel M, which wheel occupying the non-circular summit, g,- of the stem G, secures asimultancous opposing rotation of the can and agitator respectively. The periphery of the can I) is armed \vithone or more vertical or nearly vertical wings or ribs, N, which act to constantly displace the warmed portions of the ice in the annular spoc e,'0, between the can and the tub, and to leave the portions of the ice nearest to the sides of the tub comparatively undisturbed, as they should be, in order to avoid the too rapid melting of the ice. The agitator consists essentially of two blades H 1, preferably in the form ol.cyliudrical or otherwise curved segments, both on one side of and having their conoavities presented towards a common axial plane. Of these blades the blade H extends from the centre to some distance from the concavity of the can, while the'blade I is supported by arms 2' i, with its inner edge some distance from the centre, and with its outer edge nearly scraping the concavity of the can.

The action of this agitator is to'most rapidly and effectually beat up and cool the cream, the blade operating to drive the cream against the concave sides of the can, and the blade I to scrape thethus cooled portions from the sides and compel them to seek the middle of the can and to pass between-the inner edges of the blades, to he again pressed and abraded against the said sides.

While selecting the preferred form for illustration, I reserve the right to vary the same so long as the some results"-ar'e obtained by means substantially equivalent; for example, instead of the agitator and canv revolving in opposite directions, the agitator can be fixed and the can may rotate around it, or vice cergm- The blades of the-agitator instead of being curved as represented, may be flat, or nearly so. I claim herein as new, and'of my invention I The combination of the concave scraper I to remove the frozen cream from the walls of the can D,-thcp convex agitator 11 extending from near the centre of said can arranged with a space, 2',- between them, and

adapted to operate as herein described.

f In testimony of which invention I hereunto set my hand.
